I just went through the same issue/s with my truck!:eek: Two IP's, two LP's tank cleaning, CPS, PMD's, grounds, Relays, all the related fuses & connections etc., etc. After a solid 6 plus weeks of troubleshooting (thanks to all on this site:thumbsup:) The last item checked was the ECM/PCM and...

Greetings all, after all the awesome input from all of you I got big red running! after installing a new IP (twice), CPS, fuel relay, new PMD, checking (and cleaning):h) every single ground, replacing fuses, checking all related wires, new LP, blowing small amount of air through fuel line to...

Dave, did you ever get your Suburban running? If so, what was the problem??

Thanks for the information indy, I'm just a weekend warrior as well:thumbsup: but it makes sense. When I was installing the IP I did not realize there were two pin holes for the pump on the IP gear and I installed the IP in the wrong hole (bolt holes did not line up), realizing the mistake I...

That is what I am thinking, I for sure got the IP pin in the right place, all three bolts went in just right:smile5:I guess I've got some other issues that need attention. thanks for the input ireburb, awesome write up and photos indybeck!:thumbsup:

Is the procedure the same for a 95? If so I screwed up when I installed my IP. This is my second pump, the first time I guess I got lucky (no issues started right up), this time I did everything exactly the same and the truck will not start:mad2: I now know the IP itself is not at TDC nor was...

Sorry for the stupidity, BTNF? What is that?:confused:

Greetings all, quick question, should my lift pump start running the moment I turn my key to the on/start postion? Mine does not, it won't run until I build up oil pressure then it pumps like crazy.

Matuva, for the first time in months you have made me smile/laugh about these engines.....Thank you!):h I have tried everything else and your awesome story of how the engine system failed is almost indentical to my woes:mad2: Thanks so much for the great narration on how to change a CPS I have...

The reason I asked is that I'm almost having the same exact problem minus the PMD issue and stalling! Have checked everything (from the fuel tank on) except the CPS. I was thinking my IP had failed after only 1500 or so miles. So the CPS is PITA to change, how many hours & minutes and how can I...

How hard is the CPS to replace?

Thanks all of you, Missy good wrench I thought about the filter as well and replaced with a new one just in case. When I pulled the filter it was pretty clean (less than 2,000 miles) but I changed it anyway & purged the system, still surging. I'll check all of the other areas mentioned by all of...

Turbine Doc, the PMD was under the hood for a short period of time attached to SS Diesels heatsink. Bill at Health Diesel told me to get it out of the engine compartment completely, so it is now behind the bumper attached to the heatsink. I replaced it with new PMD (Ditech) that I got with the...

Greetings all, Back from working night shifts and thanks to all of you I solved the problem with the short glow plug run time. It is amazing what a loose connection will or won't do!):h Now I have a much bigger problem:mad2: About two weeks ago I was just cruising down the road at around 35 MPH...

Buddy, thanks! That makes sense, I have tried everything else. I'll go through the system/s, w/multimeter & check continuity across grounds, battery, etc. Thanks for all the help, all of you!:thumbsup: I'll have to wait a day or two before I do this (currently working nights:mad2:). I'll keep...

Good idea mitchedo, I'll check the glow plug connections again. Buddy I'll take some pics and post them. I am definitly not a pro (or even a novice!) at describing malfunctioning relays but I'll try. Tapping the relay goes back to my old ford days and their starters. These relay sometimes...

Thanks Matt & Odlaw, the injectors have less the five hundred mile on them, and I think the glow plug controler was fried when the strangely wired glow plug override system overheated (everything got really hot). The reason I think the controler has failed is intermittent function, it works...

LOL):h, Thanks for the words of encouragement! I should have told everyone my rig does start and I assume easy (not knowing how other 6.5's start), there is just a lot of white and black smoke for the first few seconds when bone cold, but still smooth. It could sit for five to six hours after...

Thanks guys, all of these are good areas to focus on. I am using the Bosch Duraterm GP's from Heath Diesel. The temps in the SF Bay area in some areas can get into the teens but never below zero. I'm gonna check the coolant temp sensor (never thought of that!). Question, if the coolant temp...

Thank you all for the quick response wow I found a home! ak diesel driver you are correct it is not a manual overide system, it is tied directly into the ignition system i.e. key on, system functioning. Everything on The override system is set up like just like a manual override with the...
